PROCESS OF LAYING PAVEMENTS.

SPECIFICATION forming part of Letters Patent No. 289,295,0late d November 27, 1883.

Application filed August 17, 1883. (No model.)

' lowing is a specification.

My invention relates to that class of pavements which are made up of various components usually in a comminuted form, called concrete, and it has for its object to provide means whereby encaustic tiles and other ornamented or plain tiles and stones may he laid, in combination with any kind of concrete to form sidewalks or other pavements.

To this end my invention consists in the process of making pavement, hereinafter de-.

scribed and claimed, reference being had to the accompanying drawing, which is a plan View of a portion of sidewalk, illustrating my method of laying pavement.

The ground is first prepared in whatever manner may be required to suit the characteristics of the ground in that locality, and the purpose for which the pavement, when laid, is to be used, the only requirement in this respect being that the ground be leveled to form a bed, allowing for the thickness of the concrete.

Suppose the pavement to be laid is for a sidewalk: Let A represent the curbstone or border, and B the building or inner line. Let 0 represent the commencing-line, and D the plank used to control the concrete and keep the blocks E and F in place. Let E and F represent the triangular blocks used to form spaces for the insertion of tiles or concrete blocks of different colors or patterns, and to control the cracking or parting of the pavement; these blocks to be of the same thick ness as the concrete portion of the pavement, and placed at such distances along the side of the plank and commencing-line as will inclose'a section to be worked, the width of the plank to be of the thickness of the concrete to be laid. Now, fill the section with concrete mortar, H, work the surface smooth with trowel or other tool, and as soon as the concrete is sufficiently set remove the blank D and blocks E and F, and plaster, coat, or wash the edges of the pavement with common clay brought to the proper consistency, either with brush or other suitable tool, such as trowel, or the like. Now, in place of the blocks E, insert a square block, and in place of blocks F insert triangular blocks E. ,On the working side of the section place the plank D at the proper distance, with blocks E and F in line, and proceed with work as before.

It is intended that each section shall form one inseparable piece, and that these noncohesive partitions shall allow each section to shrink or change its level relative to con= tiguous sections without breaking the tiles or concrete blocks forming the sections H.

The spaces formed by removing the blocks E F and square blocks may be filled with concrete of any desired color, or with encaustic tiles of any desired pattern or color.

The use of the cross-plank D in forming concrete is common, and the placing of blocks in the work is for the double purpose of a1 lowing the ornamentation of the pavement itself, and to control the cracking of the concrete. Tiles of other forms than those shown may be used, and the concrete portion of the pavement may be varied in form or color as fancy mayldictate.

I am aware'that concrete pavement has i been made in sections parted from each other by tarred paper; also, that vertically-tapering patterns have been surrounded, excepting only their top and bottom, by concrete, and removed after the concrete is set, to admit tiles shaped. like said pattern, and I do not claim the same as my invention.

What I claim as my invention, and wish to secure by Letters Patent, is

The process of making pavement which consists in, first, placing'upon a prepared ground two or more straight-edges or other strips as boundaries for the first section of the pavement, one of which boundaries may be permanent; secondly, placing within and against these boundaries pattern-blocks, each in the form of about one-half of the tile intended to take 'its place; thirdly, in filling the space between the boundaries thus formed with concrete in the form of mortar, and allowing it to set; fourthly, in moving the bounterns on the one side and the concrete and dary and the pattern-blocks to the distance half the outlines of the tiles on the other, as required for another block ofconcrete; fifthly, 1' shown and described.

in placing tiles into the half-molds formed, L T allowing them to project into the space for W ILLLUI MCLEAL' the next block; sixthly, in thinly coating the Vitnesses:
